To all whom it may concern.- tion' having the invention applied thereto,

Beitknown that I, 'WILL XV. DALE, acitizen parts being broken away so as to disclose the of the United States, residing at Fostoria, in connection of the invention.

To simplify the disclosure of the coin-controlled mechanism applied to the teleinvention, the shaft carrying the disk or plate phone before the latter can be brought into having the projections to be engaged by the requisition. coin will be designated as the power-shaft,

The invention consists, primarily, of a whether it carries the armature of the mag- 2 5 crank-shaf t having a coin-receiving pocket neto-machine or is supplied with a gear-wheel which is open at two sides, and a plate or disk for augumenting the speed of the said armamounted upon the armature-shaft of the magture.

The invention also consists of a stop for The crank-shaft 3, so designated because limiting the rotation of the crank-shaft and the operating-crank 2 is applied to the profor properly positioning the coin-pocket, and jecting end thereof, is in alinement with the 4c in a spring for returning the coin-pocket to power-shaft 1 and has the coin-pocket at afan initial or normal position after the operatfixed thereto, said pocket being radially dising-crank has been released. posed and closed on all sides except the outer The many objects and advantages attendand inner sides, which are designed to receive ant upon the practice of the invention will the coin and admit of the latter engaging 5 5 become apparent as the nature of the latter with one of the projections 5 on the plate or is understood, and for a complete disclosure disk 6 carried by the power-shaft 1. The prothereofj reference is to be had to the followjections 5 taper to a sharp edge, so as to preing description, and the drawings hereto atvent the lodgment of the coin thereon, and tached, in whichthe walls of the coin-pocket flare slightly to o Figure 1 is a front elevation of a magneto ward the inner open side, so as to admit of the call-box of common and well-known construccoin 7 having a slight lateral play, so as to clear the end of the projection opposite the inner open side of the pocket when the said coin is introduced into the outer open side or end of the pocket through the slot 8 in the casing 9, made fast to the side of the call-box.

The casing 9 is closed at its lower end bya sliding door 10, which is locked so as to be opened only by duly-authorized persons when making collection of the coins deposited therein. The slot 8 is at the upper end of the casing, and the coin-pocket 4 normally occupies a position so that its outer open side or end comes opposite or alines with the slot 8, so as to receive the coin when the latter is passed through the said slot. A stop 11, secured to a side of the casing 9, engages with the coin-pocket and holds the latter with its outer open side properly positioned opposite the slot 8, and a corresponding stop 12 is provided and engages with the said coin-pocket to limit its movement when it reaches a nearly vertical position with its outer open side or end extending downward, thereby permitting the coin to drop into the bottom of the casing and preventing it from being carried around too far to effect its discharge from the said pocket. These stops l1 and 12 are formed by bending the ends of a strip 13, which is secured to a side of the casing 9.

A coil-spring 14: has one end attached to the crank-shaft 3 and its opposite end secured in any convenient manner to a portion of the casing, and the purpose of this spring is to hold the coin-pocket against the stop 11 and in proper position opposite the slot 8, so as to receive the coin when the latter is passed through the said slot, and this spring also serves to return the coin-pocket to an initial or normal position should the crank be released atits lowermost position or at any other point not corresponding with the initial position of the coin-pocket.

The operation of the invention is as follows: When it is required to use the telephone, the

person passes a coin of proper denomination.

through the slot 8 into the coin-pocket 4, and said coin having its edge portion projecting beyond the inner open side of the coin-pocket and engaging with the projection 5 adjacent thereto, forms a lock between the crank-shaft and the power-shaft, and on turning the crank the power-shaft will be rotated and effect the result of calling up the central or the required subscriber. As soon as the coin -pocket reaches its lowermost position it will be stopped by engagement with the part 12, and the coin contain ed in the pocket will drop into the lower portion of the casin g 9, thereby disconnecting the crank and power shafts. On releasing the crank-shaft the spring 14 will regain itself and return the coin-pockct into a normal position, as will be readily understood.

Inasmuch as the invention is designed for telephonic apparatus of various kinds, it is to be understood that in adapting the same for a particular make of machine various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described the invention, what is claimed as new is- 1. In a coin-controlled apparatus for telephonic instruments, the combination with the powershaft and the crank-shaft disposed in horizontal alinement, of a vertical plate secured to the power-shaft and having a series of lateral projections on its outer face which taper on both sides to a knife-edge, and a coin-pocket secured to the crank-shaft and open on its inner and outer sides, the walls of the said pocket flaring slightly toward the inner open side, substantially as described for the purpose set forth.

2. In a coin-controlled apparatus for tele' phonic instruments, the combination with a power-shaft having a plate provided with a series of projections, and a crank-shaft disposed in horizontal alinement with the powershaft and having a coin-receiving pocket which is open on the side opposite the said plate to admit of the coin forming a lock be tween the two shafts, of a spring for returning the coin-pocket to a normal position for the proper reception of the coin and stops to limit the movements of the crank-shaft, substantially as set forth for the purpose described.

3. In a coin-controlled apparatus for telephonic instruments, the combination of a casing accessible by means ofa locked door and provided in its top side with a coin-slot, a power-shaft extending horizontally into the casing, a vertical plate secured to the powershaft and provided on its outer side with a series of projections whose sides taper uni formly to a knife-edge, a crank-shaft journaled in a wall of the casing and in the powershaft, a pocket attached to the crankshaft and open at its outer end and the side facing the vertical plate, the walls flaring slightly toward the said plate, a strip attached to the casin g and having its end portions bent to provide stops to engage with and limit the movements of the said pocket, and a spring for returning the pocket to a normal position after being actuated, and operatively connected with the crank-shaft and easing, substantially in the manner set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
